Processing & Machining Notes
The catalog describes machining PET with carbide tools and notes that process-induced stresses can cause later distortion in parts with tight tolerances.
General catalog guidance. Cutting, cooling, and heat-treatment parameters need validation for the specific grade and part.
Standards and documentation to confirm
These catalog references do not certify every grade or batch. Request the supplied grade’s document and application scope, especially for food contact, medical use, or ESD protection.
